Conrad (c) 2015</td></tr></table><hr><h4>Description</h4>Calculates for all segments of the input lines the planar, great elliptic, and loxodrome distance and re-projects the latter two to the projection of the input lines. 
Projection routines make use of the Proj.4 Cartographic Projections library.
Proj.4 was originally developed by Gerald Evenden and later continued by the United States Department of the Interior, Geological Survey (USGS).
Proj.4 Version is Rel. 4.9.3, dd Month yyyy
